This film would mark the final appearance of Ernest Morrison (Scruno) as an active member of the East Side Gang. Morrison would later appear in Follow the Leader (1944), but only in a flashback sequence using archive footage from Flying with Music (1942).
The failure of the original copyright holder to renew the film's copyright resulted in it falling into public domain, meaning that virtually anyone could duplicate and sell a VHS/DVD copy of the film. Therefore, many of the versions of this film available on the market are either severely (and usually badly) edited and/or of extremely poor quality, having been duped from second- or third-generation (or more) copies of the film.
The trivia item below may give away important plot points.
A second four-letter word made it past the censors as well. In the scene where Emil and his gang capture two of the East Side Kids, several shouts are heard as they struggle to escape. As the scene first comes into view, the first shout is a very clear exclamation using a four-letter word.
